[PATCH 0/4] mtd: spi-nor: split SFDP, ID database, and fixups

[Takahiro Kuwano via B4 Relay]

The spi-nor-core.c contains optional logics like SFDP and manufcaturer
specific fixups. The spi-nor-ids.c has single large ID database. There
are many #ifdef directives in those files and that negatively affects
readability and maintainability.

This series, as the first step of cleanup, move SFDP logic, IDs, and
fixups to newly source files. Reworking, renaming, and reformating
existing code is not a scope of this series and further cleanup will be
taken place in follow-up patches.

Here is the code size impact when applying this series.
Measured by my AMD Zynq-7000 (ARM32) environment with SFDP and all
manufcaturers are enabled.
